I have an aluminum fishing boat and I needed to re-wire the trailer lights. I used this because it was cheap. Everything was in the kit and everything fit fine. After three weeks I lost one tail light, then the other two weeks later. I checked the entire trailer for rub spots (none because I did stuff right) and went to re-do the connections to the trailer lights. When you try to strip this wire, you find out there are like 3 tiny hair-sized wire strands in it and really you mostly just bought a bunch of colored plastic sheathing. I assume the reason my lights failed is that this tiny thread of conductor material broke within the sheathing somewhere along the line. You can't even strip it without breaking the wires off. I will be going to buy another one someplace else expecting that by paying a little more I will get something with a little actual metal in it. DO NOT BUY THIS ITS NOT WORTH A PENNY.

This plugs right into the factory plug on my Toyota 4Runner. Not sure what the other reviewers are talking about with the plug not being the same design. The wires are a bit on the flimsy side but I'm sure they'll work fine. Take some extra time to route them properly providing strain relief and eliminating any sharp edges and/or kink/pinch points.

I used this to re-wire my utility trailer. It worked fine and had everything I needed but the wire is extremely thin. If you have quite a few lights I would imagine this kit won't be suitable, the lights will likely be dim and/or the wire will melt. Works fine for just hooking up tail lights.

This wire worked great on my freshwater boat trailer for a little less than one year, having installed it mid-season last year. This season I hitched up and no lights! Traced the problem to a bad trailer ground wire, no problem I figured, just strip back to some clean wire and make a new ground connection. Nope! The wire inside the insulation was corroded and pretty much just white dust. Stripped it all the way back to the plug and still no clean wire.Unbelievable! I have never seen wire completely corrode inside insulation.

I buy a lot of Harbor Freight items.Many are quite astounding for the price, like their 4x8 trailers.But, this wiring kit, which is the same one that comes with the trailers is not to be trusted.I've had two sets simply self destruct.The get the 'black creeping death' of trailer wire. (google the term to read the details)So, I can' recommend this product. HF needs to find a new supplier and remember that trailers sit outside for the most part.The wire should be pre-tinned copper.This wire appears to be copper tinned steel. And guess what? The steel rusts!

The wiring here is junk, super thin strands of copper that are weaker than human hairs. They don't tell you the gauge because it's probably below the measurable scale! AVOID! You want 18 to 16 gauge, not this weak junk!
